From 8e42f3d15c39e5c98149c9647c0cc1a318e9321a Mon Sep 17 00:00:00 2001
From: Paul Hardy <unifoundry@unifoundry.com>
Date: Thu, 23 Oct 2014 23:41:50 +0000
Subject: [PATCH] unifont-7.0.06.tar.gz

* Makefiles:
  - Updated version to 7.0.06.
  - Added "GZFLAGS = -f -9 -n" to use with gzip in all cases.
  - Changed ';' to "&&" for multiple shell commands, to fail if
    a preceding step caused an error.
  - Use "install -s" instead of "install" on C binaries.
* Makefile: regenerated .PHONY: target entries.
* font/Makefile:
  - Added GRAPHICS declaration, settable to "png" or "bmp" depending
    on the type of Unifont font pages desired.  The default is set
    to "png".
  - Added bmp: target to create bitmapped graphics (.bmp) images of
    Unifont.
  - Create font/compiled/plane00.html along with
    font/compiled/plane01.html in "png" and "bmp" targets.
* font/plane01/plane01.hex:
  - Added one glyph inadvertently omitted from Old Italic:
    U+01031F (Paul Hardy).
  - Improved animals in U+01F400..U+01F43F (Nils Dagsson Moskopp).
  - Added more scripts:
     U+010350..U+01037F Old Permic (Paul Hardy)
     U+01F650..U+01F67F Ornamental Dingbats (Paul Hardy)
     U+01F780..U+01F7FF Geometric Shapes Extended (Paul Hardy)
     U+01F800..U+01F8FF Supplemental Arrows-C (Paul Hardy)
  - Emoticons (Paul Hardy)
     U+01F608: made horns look more like horns
* src/: in all Perl scripts, added "or die" for open, close, and
  print system calls.  Made some error messages more descriptive.
* src/Makefile: Changed CFLAGS parameter "-O" to explicitly be "-O2".
* src/unihexfill: added "set -e" at beginning of bash script.

+2014-10-23: Release 7.0.06
+
+   A few new scripts were added:
+      U+010350..U+01037F Old Permic
+      U+01F650..U+01F67F Ornamental Dingbats
+      U+01F780..U+01F7FF Geometrical Shapes Extended
+      U+01F800..U+01F8FF Supplemental Arrows-C
+
+   Various changes were made to Makefiles, Perl scripts, and one bash
+   shell script to conform to Debian Policy Manual version 3.9.6.
+
+   Several changes were made to Makefiles:
+      * Use "set -e" at the start of multi-command shell invocations,
+        to trap errors.
+      * Use "&&" rather than ";" in multi-command shell invocations,
+        to fail on errors.
+      * install now uses "-s" flag for C program binaries.
+
+   Other minor changes were made to scripts; see ChangeLog
+   for details.
+
